The instructor selects from a menu of heart and lung conditions by wireless remote control. The manikin presents itself as a real patient without visible auscultation sites. The student must palpate to identify correct auscultation locations, and will hear different heart and lung sounds as the Smartscope™ is moved to different locations on the manikin. A diagnosis of the condition selected by the instructor can be made by comparing the variations in sounds occurring at different sites—just like a real patient. Lung sounds can be detected at 5 anterior, 10 posterior, and 2 midaxillary locations. Students can practice auscultation at 6 anterior heart sites. The remote control does not have to be pointed directly at the manikin or SmartScope to operate. One remote control will operate all SmartScopes within a 100-ft range. Great for group instruction. Listen to the sounds by either using headpieces on the SmartScope or by connecting to an amplifier/speaker (not included). Range on the unit is up to 100 ft of remote access. Operates using 2 AA and 2 AAA batteries (included). 5-year warranty.Lung conditions to select with the remote: bronchovesicular, bronchial, cavernous, coarse crackle, egophony, fine crackle, friction rub, infant, mono wheeze, normal lung, pectoriloquy, pulmonary edema, rhonch, stridor, vesicular, and wheeze.Heart conditions to select with remote: aortic regurgitation, atrial septal defect, holosystolic, midsystolic, mitral stenosis, normal, PDA, pulmonary, stenosis, S3 gallop, S4 gallop, systolic click, and VSD.
